Project Description

The Sweetwater Carbon Storage Hub project is meeting CarbonSAFE Phase III project objectives through the completion of detailed carbon dioxide (CO₂) storage facility characterization and all necessary permitting for a commercial-scale, secure, geological CO₂ storage complex in the Greater Green River Basin of southwestern Wyoming. The scope of work includes a CO₂ Sources Feasibility Study; a Pipeline Front End Engineering and Design (FEED) study; a Storage Field Development Plan; and a risk assessment and mitigation plan, which will continue to be actively updated throughout the project life cycle. The project is investigating subsurface conditions and surface environment of the CO₂ storage complex. The eventual integrated commercial-scale CO₂ capture, transport, and storage hub will capture and store CO₂ from the largest proposed direct air capture (DAC) facility in the Rocky Mountains and one of the nation’s largest trona (soda ash) mines. In the project’s ideal and fully realized state the hub facility will accept CO₂ from more sources and expand the storage field to include more injection wells. This will yield economies of scale and reduce risk by following a proven hub model.

Project Benefits

This project is accelerating the development of a new commercial-scale geologic carbon storage project and associated CO₂ transport infrastructure in the Greater Green River Basin of Wyoming through a focus on the detailed site characterization and permitting stages of CarbonSAFE project development.
